\ AApplication filed February 16, 1912. Serial No. 678,103.'

To all who-m 'it mag/concern Be it known that I, EDWARD PossoN, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certainne'w and usefulImprovements; in Railway Tank-Cars, vof which the followingis aspecification.

The principal object of my invention is to provide a new and impro-vedconstruction to be used in mounting a tank upon the underframe in arailway tank car.

A Another object of my invention is to pro- 'vide means for attaching atank to the un- Jde Ijame of a railway tank car, that shall p Ovide-:forunequal expansion due to heat- 'of the tank.

n Another object-of my invention is 'to provi'def a. construction bywhich a. tank may be deta'chably mounted onthe underframe of arailway'tank car.-

These and various other objects will be understood from the followingspecification and claims, taken in connection with the accompanyingdrawings, in which-- Figure 1 is a side elevation'of a tank carcomprising my improvement, certain parts being ,broken away to show thestructure more clearly. Fig. 2 is aside elevation on an enlargedscale-of the structure that constitutes my improvement.' Fig. 3 is across section showing the impro-ved features in greater detail. Fig. 4is a similar cross section on a smaller scale, showing the parts "moreextensively.

`|`vThe underframe of the car comprises the center sill consisting ofparallel `plates lying in vertical planes and covered by a top platelG.The angle irons 17 join the .side plates of the center sill to the topplate. The flat horizontal plates 18 are' riveted to lthe upper cornersof the center sill, so that their edges project outwardly therefrom, asshown in the drawings.

The underframe of the car carries six longitudinally extending woodenmembers 25, distributed las shown in Fig. 4, which forni a cradle onwhich .thetank rests.

,The upper "flange 22 vis riveted to the 19 and the lower iange ,23overlies the out- Patented-May 5, i914.

2G goes between the flange 23 and the plate 18 and may be of any properthickness.

It will be seen that the weight of the tank is supported entirely by thewooden cradle members 25 and the function of the member 2O and itsassociated elements is to hold the tank against longitudinaldisplacement in the cradle.' f

It not infrequently happens that in cold weather or at other times itbecomes desirable to heat the oil in a tank car.v This-may be done by.immersing steam coils in the oil.

and passing steam through them. Of course,

the heating of the oil also heats the walls oil the tank and causesexpansion of the latter.

For this reason the slots 27 are provided so that the flange 22 canexpand with the tank without causing undue stress and strain on theintermediate web 21. The tank, of course, should rest securely on thewooden timbers 25 andthe shims 26 may be introduced between the plates 18 and the-flanges 23 in order to secure a properadjus'tment.

Then it is desiredto remove th-e tank from the'car underframe the bolts24 can be removed and then the channels 20 will go with the tank 19while the plates 18 will staywith the underframe. If rivets are 'used inplace of the bolts 2 4 they will have to be cut. in case the tank is tobe removed.

'This -would be a slight disadvantage which would be compensated in a`measure by the certainty that the rivets'would not become loose as boltsmight do.

It will be seen that I have provided lsimple and secure construction forconnectng the tank to the underframe, and. that 'furthermore 1I havearranged this construction so that when it is desired to remove t-he.tank from the under-frame, this can .be readily accomplished. A plateof sheet metal, designated gener-v 1. In a device ofthe classdescribed,'a car underframe, a tank supprted thereby, a platepermanently fastened tothe 'said nnderframe, "a member with a`pro]ect1ng flange 'permanently fastened to the tank,

said plate ,onthe'runderframe and I Iltiliberon the tank having holes,and securing means in said holes binding the parts together.

2. In a device of the class described, a ear underrame, a tank supportedthereby, a member with two flanges, one ange being riveted to said tankand the other flangev spaced therefrom, and securn means engaging saidspaced angeand fastening the same to the said underframe, said member wbeing siotted in from its ends between its flanges.

In testimony whereof, I have subscribed my name.
